The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking over the next couple of weeks.
Right off the bat, we’ve got a solid run of swell heading for Lakey Pipe (Lakai-Pipe). This is a reef break that loves a good SW groundswell, and that’s exactly what we’re seeing. The water is sitting at 80°F, which is bang on average for the time of year, so no nasty surprises there.
The first real standout kicks off on Tuesday morning, the 1st of September. We’re looking at a clean 7ft SW swell with a long period of 18 seconds. That’s proper groundswell energy, and with a combined energy of 2684, there’s plenty of push behind it. Wind is a light cross-offshore breeze, keeping the surface clean. This is a wave for experienced surfers only – that size and period on a reef isn’t messing around. The afternoon session on the same day holds up well too, with a 7ft SW swell and cross-off wind, making for another excellent window.
The run continues through Wednesday and Thursday, with the swell staying in the 6ft to 7ft range, all clean and cross-off in the mornings. The period drops a touch to 16 seconds, but it’s still proper groundswell. Be aware, this spot is a reef, and the crowds are often around, so get out there early if you can.
Friday the 4th sees a drop in size to around 4ft to 5ft, with a shorter period of 14 seconds. The energy dips to 748, so it’s a quieter day. Still clean in the morning, but the afternoon gets a bit of cross-chop. A good day for a rest or a mellow paddle.
We get a pulse back for the weekend. Saturday morning, the 5th, brings 6ft from the SSW, and Sunday morning the 6th bumps up to 6ft. The wind holds cross-offshore, keeping it clean. The combined energy climbs back up to over 1000, so the reef starts to wake up again.
Now, for the best of the bunch. The Monday morning, the 7th, delivers a solid 7ft SSW swell with a clean cross-off breeze. That’s another one for the experienced crew. But the real standout is the Tuesday morning, the 8th of September. The swell is a bit smaller at 4ft, but the period jumps to a very long 19 seconds. That’s pure groundswell, and the combined energy is still a hefty 2108. On a reef like Lakey Pipe, that long period will produce some beautifully lined up waves. And the wind is light and cross-off. This is a gem of a session.
The rest of the second week stays consistent. The mornings from the 9th to the 16th of September are almost all clean and cross-off, with swell heights bouncing between 5ft and 7ft. The periods hold steady around 15 to 17 seconds. The afternoons can get a bit of cross-chop, but the mornings are your ticket. The week of the 15th and 16th looks particularly clean, with light winds and great conditions for experienced surfers across the board.
All in all, this is a fantastic run for Lakey Pipe. The consistency is excellent, the swell direction is bang on the optimum, and the cross-offshore winds are a gift. If you’re an experienced surfer, you’ve got a full window of opportunity here. The only thing to watch out for is the crowds that are often on this spot, but the quality of the surf will make it worthwhile.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
